Title: Image processor
Inventor: MAEDA MAMORU
IPC: G06T5/00
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To flexibly constitute an output converting part while removing a texture generated by the base level of input image when processing multigradation image data through an error diffusion method. SOLUTION: A differentiator 10 outputs differential data PS removing the component of base level from a multilevel input image PI, and an adder 20 outputs added data Pa adding the differential data PS and an error output Erout from an error computing element 40. An output converter 30 finds a multilevel output image Pout and an error input Erin of the error computing element 40 based on the added data Pa, and the error computing element 40 outputs the error output Erout weighing the error input Erin to the adder 20. The output table and error table of output converter 30 are composed of one table, and every bit width of multilevel output data Pout and error data Erin can be changed.

Title: Waveform shaping circuit
Inventor: MAEDA KEIJI
IPC: H04B10/556
Filed: 1988-05-27
Abstract: PURPOSE:To prevent transmission error due to accumulation of waveform distortion by sampling an input signal at a period of an integral number of multiple of that of the input signal and sampling and outputting the input signal at the leading of a clock having the same frequency as that of the input signal speed leading at that point of time when the input signal is consecutively detected. CONSTITUTION:An inputted signal is sampled by a counter 24 by using a clock signal having a speed being an integral number of multiple of the transmission speed from a clock signal generating circuit 21 and a D flip-flop 29 is provided, which uses an output of a counter 24 started when the 'presence' of the signal is detected consecutively for a prescribed period decided by the signal transmission speed, and stopped when the 'absence' of the input signal is detected consecutively for a period sufficiently longer than the signal 'absence' period at the normal transmission and whose frequency is equal to the transmission speed as a T terminal input and uses the input signal as a D terminal input. Thus, the input signal is passed through transparently, a waveform distortion is eliminated and the occurrence of transmission error due to accumulation of waveform distortion is prevented in advance.

Abstract: PURPOSE:To gradually work the withdrawal of a brake pad arm from a holder and the effect of the brake pad arm upon the holder by making the brake pad arm out of a shape memory alloy in its spring for attaching and detaching the holder. CONSTITUTION:When a heater 6 is to be heated up, the spring 5 made of the shape memory alloy positioned in the vicinity of this heater 6 is to be moved in its withdrawing motion shrinking with heat radiated by the heater 6, i.e. the movement of shrinking withdrawal. Force in the direction of an arrow 11 caused by shrinking and withdrawing the spring 5 is increased to be stronger than force of a spring 4 in the direction of an arrow 12, i.e. pressing force of the brake pad arm 3 against the holder 2, thus moving the brake pad arm 3 in the direction of the arrow 11. The brake pad arm 3 is withdrawn from the holder 2 so that the holder is under the released state, releasing itself from this lock while a spindle motor 1 is put under the movable state. By this method, the withdrawal of the brake pad from the holder 2 can gradually be performed in course of time without creating a sudden locking action.

Title: Color cathode-ray tube and manufacture therefor
Inventor: TAI NOBUYUKI
IPC: H01J9/227
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To improve white uniformity of a color cathode-ray tube on which an electron beam passing hole of a shadow mask is a circular shape and a fluorescent screen is composed of a dot-shaped phosphor layer by forming an electron beam passing hole of a central part of the shadow mask relatively smaller than an electron beam passing hole of the other part. SOLUTION: When a circular pattern corresponding to a circular electron beam passing hole of a shadow mask 25 is printed on a photosensitive fluorescent screen forming layer formed on an inside surface of a panel 20, an electron beam passing hole of a central part of the shadow mask 25 is formed smaller than an electron beam passing hole of the other part. Therefore, transmissivity of a central part of a light distribution filter arranged in an exposing device deviates from the originally required transmissivity distribution, and even if it is undesirably flattened, since a clearance of a matrix-shaped light unemitting layer of the central part of the panel 20 and a dot-shaped phosphor layer can be formed in the almost same size as the other part, white uniformity of the whole image screen can be uniformized.

IPC: G06F13/16
Filed: 1982-07-29
Abstract: PURPOSE:To utilize a control bus effectively for data transfer by providing a register wherein requests transferred from a CPU and plural modules through the control bus are stacked successively. CONSTITUTION:When the CPU1 outputs a request to read, the control bus 5 is used exclusively for the request, which is stacked in the register 7. A control circuit 8 drives a storage part 9 unless there is another request, and starts processing the request to read. When either of modules 3 and 4 outputs a request to write, the bus 5 is used exclusively for the request, which is stacked in the register 7. Then, the circuit 8 outputs read data to the request to read to a data bus 6. The circuit starts operation to the request to write stacked in the register 7 after outputting the read data. Thus, the circuit 8 reads a stacked request even during operation right after the operation to one request, and then performs corresponding operation.

Abstract: PURPOSE:To improve heat exchanging efficiency by utilizing dew condensate by a method wherein water absorbing member of an evaporation type air cooler is coated with a covering member which is prominent in the heat conductivity and this covering member is brought into contact with an outdoor side heat exchanger. CONSTITUTION:Dew condensate generated in an indoor heat exchanger 3 is led by a drain pipe 8 to be absorbed, and exposed to an cooling airstream (a) from a fan 2 to be vaporized. As the dew condensate absorbs latent heat during its vaporization, the cooling airstream (a) is cooled, and therefore, cooling effect by the cooling airstream (a) of an outdoor heat exchanger 1 is increased. Thus the efficiency of the heat exchange due to refrigerant condensation of the outdoor heat exchanger 1 can be increased. Further, as a covering member 12 made of a material prominent in the heat conductivity to cover the surface of a water absorbing member 10 is kept in contact with the outdoor heat exchanger 1, heat of the outdoor heat exchanger 1 is transmitted to the dew condensate which has invaded the water absorbing member 10 through the covering member 12, and therefore, the outdoor heat exchanger 1 can be cooled efficiently.
